Unacceptable list separator when loading Family Types FIX

I received the 'Unacceptable list separator' error while trying to:

• load a family from file into a project, and
• load types into the family from a Type Catalog.

I assumed the problem was to do with Type Catalog.  The family I was trying to load was from the 'Australia' default content - 

Australia\Structural\Framing\Steel\CHS-Circular Hollow Sections (AS 1163).rfa

To fix this issue I followed these steps:

1. Open the Family
2. Export the Types to a Type Catalog file.  The exported Type Catalog should only include one type, but the syntax should be correct...
3. Open the exported Type Catalog in Excel - as a comma-delimited file
4. Open the ORIGINAL Type Catalog in Excel - as a comma-delimited file
5. Copy the fields from the 'Original' default Type Catalog into your new 'fixed' Type Catalog (there may be more columns in the 'fixed' version, just Auto-Fill the other fields as necessary)
6. In Excel, save the 'fixed' version as:
   Other Formats - CSV (MS-DOS)
7. After closing the file, rename it so that .TXT is its extension.
8. Use this fixed Type Catalog to load all of the types into the opened Family.
